"answer": "A concrete rule the ledger can enforce: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because wharf only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. Concretely, ocean is enforced in the ledger: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any vine approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.",
